Decide the content of next video (Patreon)

Since the mold video was somewhat of a success I ordered this set to test for mold/bacteria on surfaces. I can swap different surfaces and than grow out mold and bacteria colonies on the agar plates.

I have 10 plates and I want to test:

1. cellphone
2. toilet seat
3. Shoes
4 - 10. ???

any suggestions. It should also work to detect mold spores in the air by just placing the agar plate open for 1 hour.

It will take a while before this will be delivered so might not be next video but the one after that.
